애플리케이션

Phenol protecting group in the synthesis of laterifluorones.

Used to prepare a SEM-ether which was, in turn, removed with BBr₃ and cyclized to a benzo-oxapane.

특징 및 장점

Convenient hydroxyl-protecting reagent. SEM-ethers are stable over a wide pH range, and can be selectively cleaved with fluoride ion under mild aprotic conditions.
